There are almost as many DC connectors as there are module suppliers. Until now, you, as installer, must always have the correct connector available as well as the appropriate adaptor and often also expensive special tools. This changes dramatically with the new SUNCLIX DC connector system.

Strip, push the connector on, plug in, screw on - finished. Why complicated, when simplicity works too? The answer to this question is SUNCLIX and was presented at this year`s Intersolar: a DC connector system that embraces all practical requirements of PV installation. It fits onto almost every cable, is easy to assemble and gives a secure and reliable connection. Connector and socket interlock automatically, unlocking is performed with a simple screw driver. And naturally it also works when several connection plugs sit close to one another.


The SUNCLIX connectors are are suitable for both flexible and stiff cables. The cable cross section can be between 2.5 to 6 mm2.

Assembled in no time at all

The assembly onto the DC cable takes place tool-free, quickly and simply: strip the cable and feed into the open connector. Firmly push the spring clamp down and lock. Now just push the connector together and screw on the strain relief - finished! For the assembly you don`t need either crimp pliers or other special tools. Another advantage: if the cable has not been pushed in far enough, the clamping procedure is easy to repeat. For this you loosen the clamp spring with a standard screwdriver and open it up again.

Standard conforming and safe!

You can rely on the SUNCLIX connector: it satisfies all requirements of the new PV connector standard DIN EN 50521, for example in regard to UV resistance, moisture protection and temperature resistance. Also in relation to current capability it measures up: 40 amps is no problem - with a cable cross section of
4 mm2 and an ambient temperature of up to 85° C. A further safety advantage: the convenient visual control of the cable connection. When the connector plug is open, the clamp mechanism is visible, in order that you can easily check the correct positioning of the electrical connection.

Free and fitted as standard

SMA equips all new inverter types with SUNCLIX connectors as standard, starting with the Sunny Tripower. Existing device lines will be adapted step for step in the coming year, the appropriate SUNCLIX field connector enclosed with the devices free of charge. You therefore save twice with SUNCLIX: no extra costs for field connectors and adaptors plus time savings via the considerably lower installation times.
